Research Priorities in the Area of Wastewater Treatment

In basic research projects, the Wastewater and Sewage Sludge Treatment research group pursues the goal of developing and testing pioneering processes and technical concepts for the municipal and industrial sectors. The aim is to increase the process and resource efficiency of existing systems.

A high priority is also given to applied aspects, for example in our consulting activities and research collaborations with operators of wastewater treatment plants as well as industry and engineering companies. Plant sizes vary from laboratory-scale plants and extend all the way to large-scale plants.
